A new mathematical model helps to advance the centuries-old art of knitting

Scientists at Europe’s famous particle collider briefly created gold ions from lead in a modern twist on the alchemical goal

The sun has produced stunning auroras on Earth in recent years as solar activity has peaked—but expect more in coming years

Galaxies come in many shapes and sizes, and trying to define them is difficult

Brookhaven National Laboratory is pushing the boundaries of particle physics.

Kosmos-482, a failed mission to Venus from the former Soviet Union that stalled in Earth orbit in the 1970s, is about to fall back to our planet. Exactly where or when it will strike, however, remains unknown

After billions of dollars in spending and decades of planning, NASA may be forced to abandon precious samples of air, rock and soil on the Martian surface. Experts are furious
